ServiceStack AutoQuery not working for DateTime values - servicestack

Question

I have a ServiceStack service using autoquery where the DateTime greater than or less than are being ignored.
Here is my request DTO:
public class GetSources : QueryBase<DbSource, Source>
{
public string Name { get; set; }
public string NameContains { get; set; }
public string NameStartsWith { get; set; }
public DateTime? LastUpdatedDateGreaterThan { get; set; }
public DateTime? LastUpdatedDateLessThan { get; set; }
}
The database table poco generated from the ormlite T4 template looks like this:
[Alias("DbSources")]
[Schema("SomeSchema")]
public partial class DbSource
{
[AutoIncrement]
public int Id { get; set;}
[Required]
public string Name { get; set;}
[Required]
public DateTime LastUpdatedDate { get; set;}
}
In the service I do some validation and then use AutoQuery like this:
var q = AutoQuery.CreateQuery(dto, Request.GetRequestParams());
q.Join<DbSource, CompanySource>((source, companySource) => source.Id == companySource.SourceId && companySource.CompanyID == companyId);
return AutoQuery.Execute(dto, q);
I'm using mstest
[TestMethod]
public void GetSources_LastUpdatedGreaterThan()
{
var expected = DateTime.Now;
var query = new GetSources { LastUpdatedDateGreaterThan = expected};
QueryResponse<Source> result;
using (var service = appHost.Container.Resolve<SourceService>())
{
service.Request = new MockHttpRequest();
result = service.Any(query);
}
log.Info(result.ToJson());
result.Results.ForEach(src => Assert.IsTrue(src.LastUpdatedDate > expected));
}
Name, NameContains, and NameStartsWith all work as expected in other tests, but both LastUpdatedDateGreaterThan and LastUpdatedDateLessThan do not generate a where clause. In my AutoQuery setup all of the properties are defaults except for EnableUntypedQueries which is false.
I know I can explicitly add the where for them in the service. i.e.
q.Where(source => source.LastUpdatedDate > dto.LastUpdatedDateGreaterThan);
But if possible I would like AutoQuery to take care of it. Does DateTime work with AutoQuery? Or am I doing something wrong in my code.

Answer 1

I ran through the Servicestack AutoQuery unit tests that mythz created using sql server. I tested using a database view which my original project was querying against and I wasn't able to replicate the issue I'm having. For now I'm going to just add the QueryField attribute to the DateTime properties on the Query model like this:
[QueryField(Template = "{Field} > {Value}", Field = "LastUpdatedDate")]
public DateTime? LastUpdatedDateGreaterThan { get; set; }
Adding the attribute gives me what I need. I'll spend some time tracking down the culprit in my code later.
